METAL ROOFING Tl LE QR SHINGLE.

SPECIFICATION formingpart of Letterslatent No. 740,842, dated October 6, 1903.

Application filed April 27, 1903- To all whom it may concern:

Be itknown that I, ALBERT FRIEDLEY, a citizen of the United States, residing at N o.

487 West Congress street, in the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Metal Roofing Tiles or Shingles, of whichthe following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of thisinvention is to provide an improved form of metal roofing tile orshingle adapted to interlock and afford practically water-tight junctions without soldering.

It consists in the features of construction set out in the claims.

In the drawings, Figure 1 is a plan View showing three of my improved tile-sections interlocked as in the practical construction of a roof therewith; Fig. 2 is a section at the line 2 2 on Fig. 1. Fig. 3 is asection at the line 33 on Fig. 1. Fig. 4 is a section at the line 4 4 on Fig. 1. Fig. 5 is a detail similar to Fig. 2,

showing the seam closed. Fig. 6 is a detail similar to Fig. 3, showing the seam closed.

I have illustrated my invention as applied to metal roofing tiles or plates which are in form oblong equilateral hexag'ons and are designed to be arranged on the roof with their longest diagonaland the two opposite parallel sides extending up and down on the roof- 2'. e., in the direction of-maximum slopewhich direction is for convenience of reference hereinafter termed longitudinal, such tiles being placed in transverse rows with their said opposite parallel edges abutting and joined, whereby there are formed between each two consecutive tiles in each row reentrant angles equal to the minimum angles of the plates, respectively, and adapted thereby to receive such angles of the tiles'of the next row above and below. In the drawings each of these hexagonal plates 1 has the opposite parallel longitudinal edges formed so that one of said edges of each plate is adapted to interlock with the'other of said edges of the adjacent plate to form an upstanding rib-seam. For this purpose at one of said edges the metal is folded upward and refolded down inwardi. c., on the side toward the body of the plateformingadownsuch rib seam.

Serial No. 154,407. (No model.)

wardly-open element 2, and the other of said edges is folded upward and refolded down outwardly and back again upwardly between said first two folds, forming the element 3 of These two elements are adapted to be united by longitudinal sliding of the former within the latter, so that they are interlocked, as seen in Fig. 2, and the two plates thus united are inseparable except by the same longitudinal movement by which they were engaged. The two upper edges of each plate are folded back upwardly, forming flanges 4 4, and the two lower edges are folded back inwardly, forming flanges 5 5.

The flanges 4 4 do not extend to the geometrical angles or corners of the hexagonal outline of the plate; but at the upper apex of each plate between the two flanges 4: 4 the plate is extended to form a lug 6, and at the lower end of each flange the metal of the plate is left unfolded for a short distance, forming, after apex between the flanges 5 5 of the lower sides, forming a hollow upstanding boss or rib 10 of sufficient height to stride or saddle upon the upper end of the rib-seam formed by the interlocking of the elements 2 and 3. Either or both of the pairs of flanges at the upper and lower sidesto wit, flanges 4 4 and 5 5--are left projecting somewhat obliquely in the original formation of said flanges, and after the mounting of one transverse row of plates on the roof the next row above is engaged by lodging the hollow boss or saddle 10 of another plate over the rib-seam 2 3 and moving the plate thus lodged upward to engage its flanges 5 5 under the flanges 4 4 of two adjacent plates of the first row. This interlocking, it will be seen, can be performed at the finish of the longitudinal movement, by which the seam elements 2 3 of each two adjacent plates of the second row are interlocked, as described. The plates may be secured to the roof by nails through the lugs 6 and 7, and these nails will be covered in the case of each plate by the application of the next succeeding plate above. The rib-seams formed by the interlocking of the elements 2 and 3 will be closed together by proper appliances for clenching such seams, either as the seams are formed successively or as a row of plates is completed, this being preferably done before the application of the next row above, so that the seam may be closed up to the end under the saddle 10, as well as at the uncovered port-ion below such saddle. The lapped seams made by the engagement of thefianges 5 under the flanges 4 will also be'securely closed by hammering as each plate or row of plates is put in place and secured by the nails through the lugs at the upper side. a By this means it will be seen that each plate is adapted to shed the water onto the next plate below at a distance beyond any lap or seam through which it might pass and that each plate so protects the plates which it overlaps at the lower edge that in case of rain driven by the wind upward or against the slope of the roof it cannot pass these seams without being obliged to follow a very circuitous path around through the folds or interlappings of the plates, which are joined at said seams. The structure is thereby adapted to make a Water'tight roof without soldering.

I claim- 1. A roof comprising hexagonal tiles which are joined successively in transverse rows by doubly interlocking upstanding rib-seams at their longitudinal edges, and by interlapping fiat seams at their oblique upper and lower edges.

2. A metal-tile roof comprising hexagonal metal tiles having their opposite parallel longitudinal edges formed respectively with an upturned flange refolded inwardly upon itself and overhanging the plate, and an upstanding flange refolded outwardly downward and inwardly upward, the former adapted to be interlocked with the latter by endwise sliding 4o engagement to form longitudinal upstanding rib-seams, the upper and lower oblique edges ofsaid tiles being provided with flanges which are refiexed outward and inward respectively, whereby they are adapted to be engaged by broadside movement of the one toward the other in the endwise interlocking movement of the longitudinal edges.

3. In a metal-tile roof, hexagonal metal tiles having upstanding reflexed flanges at their opposite lateral edges, adapted to interlock endwise to form longitudinal upstanding ribseams between the adjacent tile of each transverse row, and'having at their upper and lower oblique edges flanges reflexed outwardly and inwardly respectively, and having terminating at the lower apex the longitudinal upstanding hollow boss or saddle, 10, adapted to stride the upstanding rib-seam of the next lower row.

4. In a metal-tile roof, hexagonal metal tiles having their adjacent edges correspondingly flanged for interlocking with the tiles of each row overlapping at their lower edges the adjacent tiles of the next lower row, and having at their upper edges lugs projecting upwardly beyond the fold-lines of the interlocking flanges to afford means for securing each tile to the roof underneath the next overlapping tile.

In testimony whereof I have hereunto set my hand, in the presence of two witnesses, at Chicago, Illinois, this 22d day of April, A. D.
